* New upstream version.
+ Prevent unauthorized code execution during pg_dump (Masahiko Sawada)
An attacker able to create and drop non-temporary objects could inject
SQL code that would be executed by a concurrent pg_dump session with the
privileges of the role running pg_dump (which is often a superuser).
The attack involves replacing a sequence or similar object with a view
or foreign table that will execute malicious code. To prevent this,
introduce a new server parameter restrict_nonsystem_relation_kind that
can disable expansion of non-builtin views as well as access to foreign
tables, and teach pg_dump to set it when available. Note that the
attack is prevented only if both pg_dump and the server it is dumping
from are new enough to have this fix.

* New upstream version.
+ Restrict visibility of pg_stats_ext and pg_stats_ext_exprs entries to
the table owner (Nathan Bossart)
These views failed to hide statistics for expressions that involve
columns the accessing user does not have permission to read. View
columns such as most_common_vals might expose security-relevant data.
The potential interactions here are not fully clear, so in the interest
of erring on the side of safety, make rows in these views visible only
to the owner of the associated table.
The PostgreSQL Project thanks Lukas Fittl for reporting this problem.
(CVE-2024-4317)
By itself, this fix will only fix the behavior in newly initdb'd
database clusters. If you wish to apply this change in an existing
cluster, you will need to do the following:
In each database of the cluster, run the fix-CVE-2024-4317.sql script
as superuser. In psql this would look like
\i /usr/share/postgresql/16/fix-CVE-2024-4317.sql
Any error probably indicates that you've used the wrong script
version. It will not hurt to run the script more than once.
Do not forget to include the template0 and template1 databases, or the
vulnerability will still exist in databases you create later. To fix
template0, you'll need to temporarily make it accept connections. Do
that with
ALTER DATABASE template0 WITH ALLOW_CONNECTIONS true;
and then after fixing template0, undo it with
ALTER DATABASE template0 WITH ALLOW_CONNECTIONS false;

* Tighten security restrictions within REFRESH MATERIALIZED VIEW
CONCURRENTLY (Heikki Linnakangas)
One step of a concurrent refresh command was run under weak security
restrictions. If a materialized view's owner could persuade a superuser
or other high-privileged user to perform a concurrent refresh on that
view, the view's owner could control code executed with the privileges
of the user running REFRESH. Fix things so that all user-determined code
is run as the view's owner, as expected.
The only known exploit for this error does not work in PostgreSQL 16.0
and later, so it may be that v16 is not vulnerable in practice.

* Fix handling of unknown-type arguments in DISTINCT "any" aggregate
functions (Tom Lane)
This error led to a text-type value being interpreted as an unknown-type
value (that is, a zero-terminated string) at runtime. This could result
in disclosure of server memory following the text value.

(CVE-2023-5868)
* Detect integer overflow while computing new array dimensions
(Tom Lane)
When assigning new elements to array subscripts that are outside the
current array bounds, an undetected integer overflow could occur in edge
cases. Memory stomps that are potentially exploitable for arbitrary
code execution are possible, and so is disclosure of server memory.
The PostgreSQL Project thanks Pedro Gallegos for reporting this problem.
(CVE-2023-5869)
* Prevent the pg_signal_backend role from signalling background workers
and autovacuum processes (Noah Misch, Jelte Fennema-Nio)
The documentation says that pg_signal_backend
cannot issue signals to superuser-owned processes. It was able to
signal these background processes, though, because they advertise a
role OID of zero. Treat that as indicating superuser ownership.
The security implications of cancelling one of these process types
are fairly small so far as the core code goes (we'll just start
another one), but extensions might add background workers that are
more vulnerable.
Also ensure that the is_superuser parameter is set correctly in such
processes. No specific security consequences are known for that
oversight, but it might be significant for some extensions.

Srinivasarao for reporting this problem. (CVE-2023-5870)
* Fix misbehavior during recursive page split in GiST index build
(Heikki Linnakangas)
Fix a case where the location of a page downlink was incorrectly
tracked, and introduce some logic to allow recovering from such
situations rather than silently doing the wrong thing. This error could
result in incorrect answers from subsequent index searches. It may be
advisable to reindex all GiST indexes after installing this update.
* Prevent de-duplication of btree index entries for interval columns
There are interval values that are distinguishable but compare equal,
for example 24:00:00 and 1 day. This breaks assumptions made by btree
de-duplication, so interval columns need to be excluded from
de-duplication. This oversight can cause incorrect results from
index-only scans. Moreover, after updating amcheck will report an error
for almost all such indexes. Users should reindex any btree indexes on
interval columns.
